PATENT OFFICE PRESLEY S. COMES, JR, OF CHICAGO, ILLINOIS, ASSIGNOR TO MONORAIL ENGINEERING CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS HONOR-AIL TRACK CONSTRUCTION Substitute for forfeited application Serial .No. 154-,721, filed December 14, 1926.

This application filed October 5, 1929. Serial I10. 397,713.

This application is a substitute for application No. 154,721, filed December i l, 1926, forfeited.

The present invention relates to monorail track structures and more particularly to constructions of this kind in which the track rails are supported on Lbeams, such beams preferably having flanges of sufficient width so that the curved rails may be supported thereon without the necessity of curving the L beams. In order to secure the rails to the beams I provide novel clips which may be made in various forms in order to hold the ails in different positions laterally with respect to the I-beams. V

The objects of this invention are to provide improved clamps or clips for securing rails to I-beams; to provide an improved rail clip of this character which will be simple in construction and economical to manufacture but which will be particularly effective and durable in use; to provide a rail clip of the character indicated which is adapted for fastoning the ends of the rails to I-beams or the like and also for fastening the ends of the rail together; to provide rail clips of this character which are particularly adapted for fastening rails to Lbeams, either on tangent or curved tracks; and to provide such. further improvements and novel features as will be described more fully hereinafter.

In the accompanying drawings illustrating this invention;

Figure 1 is a plan view of a portion of rail and beam showing the clip in position;

Figure 2 is a similar view showing a modified form of clip which also serves for making a rail joint;

Figure 3 is an enlarged cross section taken on the line 83 of Figure 1;

Figure l is a plan view of a portion of track on a curve; and

Figure 5 is a sectional View taken on the line 5-5 of Figure 4:.

As shown in these drawings, the track rails (3 are supported by l-bcains 7 and in order to securely fasten these parts together, I provide fastening clips or'clamps 8 of the novel form shown. Each of these clips comprises two oppositely disposed jaws or clamping members 9 which are fastened together by one or more bolts or fastening members 10, and each clamping member has a lower substantially ll-shaped portion 11 with one or more reinforcing ribs 12. The upper face 13 of the lower portion of the clip is of approximately the same pitch or bevel as the adjacent lower surface of the flange 14: of the beam 7. The lower face 15 of the upper portion of the jaw member 11 is of approximat-ely the same pitch or bevel as the adjacent surface of the flange or base 16 of the rail 6, and the upwardly extending portion 17 of the clip or clamp is adapted to engage or fit against the sides of the rail web. The parts are so proportional that when the bolts are tightened the clips or clamping members will be drawn together and will force the rail closely against the top of the beams where it will be held securely against lateral or longitudinal movement. In most constructions, the rail will be clamped directly against the I-beam in order to deaden the noise or to make a better joint between these parts.

In making a curved track, relatively short straight sections of beams may be used, as shown in Figure i, and the rails curved. In this instance, the rail will not be centrally disposed with relation to the beam, but in order to securely fasten the same to the beam,

the clips may have clamping portions 19 and 20 of unequal length whereby the rail may be secured in any position laterally with re spect to the beam, as will be readily understood from Figure 5. p

The particular form of clamp as shown in Figure 1 is adapted to be used at frequent intervals along the rails, but at the ends of the rails the clamping members 21 are preferably made sutliciently long so that they not only serve to fasten the ends to the beams but also serve as jointmembers to splice the rails together.

By means of my improved clamps, it will be seen that the rails may be firmly bound or pressed against the beams so that any lateral movement of the rails with respect to the beams is resisted by the friction between these the clamps and bolts. Furthermore, the V- shaped clamping members Will effectively prevent the rail from being rotated or turned With respect to the beam. It Will also be noted thatmy improved clips or clamps may be made in various forms and sizes for different rails or supporting members and may also be varied in-details of construction in order to adapt them for difierent conditions,

and therefore I do not wish to be limited to the arrangement herein shown and described except as specified in the following claims, in Which I claim:

1. In a monorail track construction, the combination With a straight supporting beam, of aicurved rail mounted on-said beam, clips engaging With the-oppositely disposed flanges of said beam and rail, and fastening means for securing the clips together.

2.- The combination with an I-beam, of a rail mounted on said beam Which is narroWer than thebeam, and a fastening clamp comprising oppositely disposed clamping members having substantially V-shaped recesses iorreceiving portions of'the beam and rail and bolts for securing said members to- PRESLEY S.
